Why is a magnetic field a vector quantity?

This direction is independent of the test dipole, and only depends on the orientation and distance of the magnetic dipole. The force this unit dipole experiences, is the magnetic field at that point. As you can see, this quantity requires a unique direction for compete understanding. Therefore, it is a vector quantity.

it doesn't. it was imagined up in the middle ages.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
